On the way back to Austin, I took a different route so as to avoid the construction areas on FM 696. It was longer in miles but shorter in time.
Route: US 77 S to Lincoln => TX 21 W to Bastrop => TX 71 W to Austin
Total Miles Driven: 71
Weather Conditions: Fair and mild
Road Conditions: Good, with four or more lanes all the way
Gasoline Price: $2.959 at Austin
